* For those how are interested here's a short history of the bootstrapbase / bootstrap theme:

As
most of you know the bootstrapbase parent theme was derived from the
contributed bootstrap theme found in the Moodle plugin database.The contributed bootstrap theme was created using the (twitter) bootstrap framework from http://getbootstrap.com. One of the requirement for the theme to be adopted into Moodle core was not to have any jQuery libraries. At the time we were able to provide a YUI ported version of the bootstrap JavaScript files by Jay Shirley. They were incomplete but at least added some features.

Good idea, but as Bootstrap has no official AMD version I was stumped for M2.9 (as the 'jquery' folder mechanism is effectively depreciated). So, in the past week I experimented with Shoehorn and found an AMD port as the available grunt tasks did not work. Anyway, long story short, please see: https://github.com/bmbrands/theme_bootstrap/pull/360 for a working AMD version of the theme.

Why should there be confusion? Confusion about what? There can't be any confusion if you are installing Elegance or Shoehorn as Moodle will not let you install it without its dependancies, which is, in their case, BOOTSTRAP 3.0 theme.
